With A Modular Update, LI-COR Terrestrial Light Sensors Shine

For environmental professionals looking to measure light, the sun’s energy or photosynthetically active radiation, there is no better choice than LI-COR’s all-new line of terrestrial light sensors. The series, including the LI-190R , LI-200R and LI-210R , has been redesigned from the ground up and is more convenient, reliable and durable than ever before. The new design centers on a modular setup that lets users detach the sensor head from the base. This makes it possible to swap out sensor heads for calibration or to measure different light parameters. In addition, it adds to project flexibility, saving users time and money.

Climate Shift Shrunk Lake Mega-Chad A Millennium Ago

How did Lake Mega-Chad, once the world’s largest lake some 1,000 years ago, shrink to near its current size? The answer is that it did so quite suddenly, at least in terms of Earth’s history. Scientists at the University of London and King’s College made the find, according to a release from U. of London, after using satellite images to map long-lost shorelines of the mega lake. They also collected sediment samples along the shores to classify them by age. By putting it all together, they were able to construct a 15,000-year history of Lake Mega-Chad’s water levels.
